A few more positives he didn't mention or touched on only briefly:

- this is proven technology. test reactors of several megawatts were run (up to a year) in the mid 1960's.

- apparently these were never commercialized because the companies that build reactors (GE, Westinghouse) don't have a chance to make money selling fuel rods, so they don't want to build them (capitalism doesn't solve all possible problems)

- this technology scales from small to huge reactors, so very localized generation would be feasible in a way not possible with large conventional reactors.

- these reactors can burn up the nuclear waste we already have too much of.

- they operate at high enough temperature to directly crack water into hydrogen and oxygen for fuel.

- they produce very little waste, with a very short decay time (a few centuries instead of mega-years).

- they burn almost 100% of the fuel into energy.

- thorium is much safer to mine than uranium.

My opinion: we need to start building these as fast as possible, both to provide power, and to deal with the vast quantity of nuclear waste we have already created. I don't think we silly monkeys can safely store anything for millions of years, and counting on success with nuclear waste is an insane gamble. We can burn it, and in all sanity we must. Along the way we can solve our energy needs. Win - Win.

Go Thorium...If America can go to the moon for purely political reasons and have nothing but rocks and glory to show for it..>Then surely LFTR tech can be developed to break the fossil fuel addiction

TEDxYYC - Kirk Sorensen - Can Thorium end our energy crisis?
The TED community will respond to Kirk Sorensen and his compelling message.
The Youtube view count "Show video statistics" shows that his message has already reached the far corners of the internet in two weeks.

Definately Kirk Sorenson, on Thorium. http://www.youtube.com/watch?v=N2vzotsvvkw
If only LFTR reactors had been commercially developed sooner, we may not have had the disaster at Fukushima. This is important info for everyone.

The liquid fluoride thorium reactor is certainly a concept worth spreading because has the potential to impact the world in enormous and very positive ways, but relatively few people are aware of the technology.

I only stumbled upon this randomly via Google, trying to find the official recommendation mechanism. Looking at the main website, I see ways to recommend speakers for TED Talks (I'm guessing to appear at a big TED Talk themselves), but no way other than this thread to say "this TEDx Talk is interesting, please consider it for wider exposure".
